Delegate fight: Corzine mulling options?

Per NBC's Tom Winter, Gov. Jon Corzine, a Clinton superdelegate, just said on CNBC's Squawk Box that he reserves the right to change his vote from Hillary Clinton if she doesn't have the popular vote. He stopped short of saying that he definitely would change his vote if she lost the popular vote and he did strongly emphasize that Sen. Clinton would win the popular vote in the end.

Sen. Maria Cantwell, another Clinton super, has said similar things regarding the popular vote.
